HS Code 8405
Producer Gas and Water Gas Generators
HS code 8405 covers producer or water gas generators and acetylene gas generators, often used in industrial chemical processing and welding applications.
HS Code 8405 — Producer Gas and Water Gas Generators
This code covers industrial equipment designed to generate gas through chemical reactions involving water or air. It includes acetylene gas generators and similar water-process generators used for lighting, welding, or chemical manufacturing. Often shipped with integrated purifiers to remove impurities from the generated gas.
What's included
- Acetylene gas generators
- Producer gas generators
- Water gas generators
- Gas purifiers for generators
What's excluded
